Venus’s rift valleys could be its secret to staying active

What it means

This reports on a new scientific study proposing that Venus's rift valleys—massive crack systems in its crust—may be responsible for the planet's ongoing geological activity. Traditionally thought to be largely dormant, Venus shows signs of recent volcanism and tectonic movement, and this work suggests that heat escaping through these rift zones could drive that activity, keeping the planet 'active' in a way similar to Earth's plate tectonics but through a different mechanism.

Accuracy & sources

The claim comes directly from a primary source: a paper published in Nature, which is a leading peer-reviewed journal. The headline and note sit close to the original research, so the core finding is solid as a scientific proposal. I cannot verify the specific data or methods behind the claim from the given information alone.

How new

The publication is current—no recirculation year is indicated—so this is genuinely new research appearing in Nature (likely the issue linked below).
